It’s not only the sharpest and best low-light zoom lens we’ve tested for the a7R II, it also outperforms many FE-mount prime lens options, ranking as the fourth-sharpest lens we’ve tested on the a7R II. Resolution at f/2.8 is first-class between 100 and 200mm, and peak sharpness of over 80% acutance in the field occurs between f/4 and f/8 for phenomenally sharp results on the a7R II. Costing $2,498 and coming in at 200mm in length, and weighing nearly 1.5 kg, it’s a big beast for the diminutive a7 series of mirrorless hybrid cameras. This ssaid, it packs plenty of high-end pro features for advanced autofocus operation, image stabilization, and all-round top performance in fast-paced environments.
